Abstract

Photorefractive CdTe:V crystals are investigated in comparison with undoped CdTe and with As and Cl codoped samples by spectral response of steady-state photoconductivity at various temperatures, mainly in the near infrared region. The deep levels have been characterized. The two charge levels of vanadium, V²⁺ and V³⁺, have been identified and their roles in the photorefractivity properties determined.
